Seth's going over to the old Roadkill Library to measure the shelves to see if they'll fit the new staff room at Catty Library. Problem number one being that he doesn't know how much space there is in the staff room at Catty. And T.Aldous and Julia, who have given him the job to do, don't know either. So he's going to Catty Library first.
"While you're going to Catty I'll come with you, there's something I need to check there," says Julia.
"Oh," adds T.Aldous, "while you're going to Roadkill could you bring some booksale back?"
"No," says Seth.
"You don't have to bring it all back."
"No. I'm only going in the car, there's no room for any boxes of book sale."
"If you take the trolley you could do it."
"If I take the trolley I'll have even less space. I'm not doing it."
"Well it needs to come back here. How's it getting here?"
"You could ask the van driver to pick it up," suggests Seth.
